Unveiling Complex Chemistry in Planet-forming Disks with the SKAO

Chemical Complexity in the Early Stages of Star Formation in the SKAO Era
Eleonora Bianchi, Mathilde Bouvier, Claudio Codella +44
About 350 molecules have been identified in the interstellar medium (ISM), including complex molecules relevant to prebiotic chemistry. A remarkable level of molecular diversity ha…
FAUST XXXI. Grain properties and variability of three sources in GSS 30
Q. Yang, H. Baobab Liu, S. Feng +55

Glycolaldehyde and ethanol toward the L1157 outflow: resolved images and constraints on glycolaldehyde formation
Juliette Robuschi, Ana López-Sepulcre, Cecilia Ceccarelli +3
Two main formation routes have been proposed for interstellar complex organic molecules (iCOMs): on dust grain surfaces and in the gas phase. Observing such molecules in protostell…
Anatomy of the Class I protostar L1489 IRS with NOEMA - II. A disk replenished by a massive streamer
M. Tanious, R. Le Gal, A. Faure +3
(abridged) Streamers are newly identified channels that transport mass from large, molecular-cloud scales down to small, protoplanetary-disk scales. To better understand their impa…
The evolution of CH in Planck Galactic Cold Clumps
Gan Luo, Arshia M. Jacob, Marco Padovani +6
Methylidyne (CH) has long been considered a reliable tracer of molecular gas in the low-to-intermediate extinction range. Although extended CH 3.3 GHz emission is commonly observed…
FAUST XX. The chemical structure and temperature profile of the IRAS 4A2 hot corino at 20-50 au
J. Frediani, M. De Simone, L. Testi +20
Young low-mass protostars often possess hot corinos, compact, hot and dense regions bright in interstellar Complex Organic Molecules (iCOMs). Besides of their prebiotic role, iCOMs…
Full interferometric map of the L1157 southern outflow: Formamide (NHCHO) can form in the gas, after all
Ana López-Sepulcre, Claudio Codella, Cecilia Ceccarelli +2
The formation mechanism of interstellar formamide (NHCHO), a key prebiotic precursor, is currently a matter of hot debate within the astrochemistry community, with both gas-pha…
FAUST XVII: Super deuteration in the planet forming system IRS 63 where the streamer strikes the disk
L. Podio, C. Ceccarelli, C. Codella +55
Recent observations suggest that planets formation starts early, in protostellar disks of yrs, which are characterized by strong interactions with the environment, e.g.,…
FAUST XIII. Dusty cavity and molecular shock driven by IRS7B in the Corona Australis cluster
G. Sabatini, L. Podio, C. Codella +54
The origin of the chemical diversity observed around low-mass protostars probably resides in the earliest history of these systems. We aim to investigate the impact of protostellar…
FAUST X: Formaldehyde in the Protobinary System [BHB2007] 11: Small Scale Deuteration
Lucy Evans, Charlotte Vastel, Francisco Fontani +16
Context. Deuterium in H-bearing species is enhanced during the early stages of star formation, however, only a small number of high spatial resolution deuteration studies exist tow…
ALMA-IMF. VII. First release of the full spectral line cubes: Core kinematics traced by DCN J=(3-2)
N. Cunningham, A. Ginsburg, R. Galván-Madrid +30
ALMA-IMF is an Atacama Large Millimeter/submillimeter Array (ALMA) Large Program designed to measure the core mass function (CMF) of 15 protoclusters chosen to span their early evo…
FAUST VIII. The protostellar disk of VLA 1623-2417 W and its streamers imaged by ALMA
S. Mercimek, L. Podio, C. Codella +25
More than 50% of solar-mass stars form in multiple systems. It is therefore crucial to investigate how multiplicity affects the star and planet formation processes at the protostel…
SOLIS XVII: Jet candidate unveiled in OMC-2 and its possible link to the enhanced cosmic-ray ionisation rate
V. Lattanzi, F. O. Alves, M. Padovani +9
The study of the early phases of star and planet formation is important to understand the physical and chemical history of stellar systems such as our own. In particular, protostar…
OMC-2 FIR 4 under the microscope: Shocks, filaments, and a highly collimated jet at 100 au scales
L. Chahine, A. López-Sepulcre, L. Podio +14
Star-forming molecular clouds are characterised by the ubiquity of intertwined filaments. The filaments have been observed in both high- and low-mass star-forming regions, and are…
PRODIGE -- Envelope to disk with NOEMA I. A 3000 au streamer feeding a Class I protostar
